Title: Oxidation of paraffins to secondary aliphatic alcohols
IPC: C07C29/52
Filed: 1966-09-05
Abstract: An aliphatic secondary alcohol containing 6 to 40 carbon atoms is prepared by reacting the corresponding paraffin with molecular oxygen in the presence of a trialkoxyboroxine, hydrolysing the resulting boron containing ester to form aqueous boric acid and a secondary alcohol. Suitable trialkoxyboroxines include those wherein the alkoxy substituent contains 4 or more carbon atoms and has either at least two carbon atoms less than the paraffin, when the paraffin has less than 10 carbon atoms, or at least 4 carbon atoms less than the paraffin, when the paraffin has at least 10 carbon atoms.  The oxidation step may be carried out at elevated temperature and under pressures greater than or equal to atmospheric optionally in the presence of a catalytic amount of a heavy metal compound such as an organic salt of cobalt, manganese, lead or iron which is soluble in the reaction mixture.  Preferably at least part of the trialkoxyboroxine is obtained by partially hydrolysing a trialkyl borate ester (formed from aqueous boric acid and an alkanol of at least 4 carbon atoms), optionally in a solution of the paraffin to be oxidized, at a temperature from 130 DEG  to 225 DEG  C. in the presence of water vapour at a partial pressure of at most 250 mm. of Hg. The entire process may be carried out batchwise or continuously, the ketone by-product and unoxidized paraffin being removed from the intermediate boron containing ester prior to hydrolysis with water to give the desired secondary alcohol mixed with aqueous boric acid which may be re-converted to a trialkyl ester for re-use particularly in the specified continuous mode of operation.  The oxidation of dodecane to a secondary alcohol together with the corresponding ketone and diol by-products is described.  Tri-(n-butoxy) boroxine is prepared by controlled partial hydrolysis at elevated temperature of tri-(n-butyl) orthoborate in an atmosphere of nitrogen and water vapour.  Tri-(n-butyl) orthoborate is prepared by esterification of aqueous boric acid.

IPC: H03M13/51
Filed: 1968-08-21
Abstract: 1,221,454. Electric selective signalling. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 21 Aug., 1968 [4 Sept., 1967], No. 39939. Heading G4H. To convert an n-bit code to an m-bit constant ratio code (m>n) the n-bit word is stored in a shift register and corresponding stages of a second m-bit register are set to conditions determined by the content of the first register. The remaining stages of the second register are set to conditions determined by the number of 1-bits in the n-bit word, the second register then containing the required m-bit word. An arrangement for converting from 5-bit to 7-bit constant ratio code comprises a shift register A-E, Fig. 1, fed with the 5-bit signal from contacts 1-5. The five bits are shifted out serially and fed back go the register input and to a binary cyclic counter which counts the mark bits and consists of two bi-stable stages FF, GG which form part of a second shift register AA-GG. If the number of mark bits is 0, 1, or 5, a code converter fed by the 5-bit output of A-E causes the signal in A-E to be replaced by a different 5-bit signal, having three mark bits, and if the number is 0 the counter is reset to the binary state 10. On the other hand if the number is 2, 3, or 4, the 5-bit signal in A-E is not altered. The signal in A-E is now transferred to AA-EE so that register AA-GG contains the required 7-bit signal. In a modification AA-EE of the second register are replaced by A-E of the first register. A second embodiment, Fig. 4 (not shown), for conversion from 6-bit to 8-bit code is described and is similar to Fig. 3 with additional register stages, and a third embodiment, Fig. 4 (not shown), for conversion from 7-bit to 10-bit code is also similar. In the latter embodiment six of the 7-bits in the input signal are converted to 8-bit code, as indicated above the seventh bit causing the 8-bit signal to be augmented by binary signals 01 or 10 to provide the required 10-bit signal.

Filed: 1975-09-30
Abstract: 1494765 Plame-cutting MESSER GRIESHEIM GmbH 30 Sept 1975 [2 Oct 1974] 39948/75 Heading B3V A flame-cutting machine comprises a travelling carriage (14), Fig. 1 (not shown), with a track (16) transverse to the direction of travel, and at least one torch carriage 18 carrying at least one torch unit 20, movable along the track (16), and carrying at least one torch 26 and a scrap cutter such as torch 90, the scrap cutter being mounted directly on the torch unit 20 and operation of the scrap cutter to effect a cut being dependent upon movement of the travelling carriage of the machine. A support 24 for cutting torches 26 also supports a cylinder 36 for lifting a frame 60 supporting a scrap cutting torch 90 off a workpiece 28 against the action of springs 50 between cuts. The piston-rod of cylinder 36 is connected to a carriage 52 slidable on a rod 56 fixed to frame 60, a spring 62 urging the frame to the left as viewed in Fig. 2. A rod 80, slidably mounted on the frame for movement at right angles to movement of carriage 52, carries the torch 90 and a cam 76. A roller 74 on the carriage 52 normally engages a plane portion a of the cam face. In use, when a strip 92, trimmed from a plate 28 by torch 26, is to be severed the carriage 52 is lowered by the cylinder 36, the springs 50 urging legs 66 against the plate surface. Continued cutting movement, i.e. movement of the support 24 in the direction F, causes the carriage 52 to move to the left against the action of the spring 62, a rod 94 on the carriage releasing a switch 68. This opens the cutting oxygen supply valve for the torch 90 which heats the area to be cut until the relative movement between the carriage and the frame causes the roller 74 to move along the portion b of the cam and force the cam and thus the torch 90 across the strip 92. Actuation of a switch 70 by the rod 94 causes the cylinder 36 to raise the frame, closes the oxygen supply valve to torch 90 and sets a time relay for the next lowering of the frame.

Apparatus for dispensing a fluid medium under pressure, particularly water or a dry powder fire extinguishant, comprises a container therefor (e.g. 10, Fig. 1), a neck opening closable by a control head, 12, which is movable between an outer operational position sealing the opening and an inner venting position, a pressure surface 41 subject to the internal fluid pressure tending to urge head 12 outwards, sealing means connected to 12 and cooperating with neck 11 to seal the opening when 12 is in the outer position but ineffective in the inner position, and disengageable locking means including pin 16 which limits outward movement of 12 to the outer position and is disengageable on movement to the inner position. Metal container 10 and neck 11 are welded together and closed by plastic control head 12 formed with stepped portions 21, 22, upper part 23, axial bore 24 for syphon tube 15, and discharge passageway 25. Syphon tube 15 is controlled by valve 14. Handle 38 and valveoperating lever 39 are rigidly-pivotally mounted respectively such that valve 14 is operated by squeezing 38 and 39 together. Seal arrangement 13 includes annular formation 40 at the base of neck 11 providing cylindrical surface 41 against which acts "O" ring seal 42 mounted in annular recess 48 in step 22. The diameters of 21, 22 and 11, 40 are such as to provide a vent passageway from the container interior to atmosphere when control head 12 is depressed, shoulder 43 limiting the extent of depression. In Figs. 1-3 the locking means includes U- shaped pin 16 a pair of diametrically opposite vertical slots 44, 45 in control head part 20 and similar slots 46, 47 and 49, 50 in neck 11 aligned with 44 and 45 respectively. The pin arms 51, 52 extend through 44-46-47, and 45-49-50, and are bent where they emerge from neck 11 to form obstructing sections 55, 56 which prevent withdrawal of the pin. The slots are arranged to be in alignment for pin withdrawal only when 'O' ring 42 is below surface 41. Normal container pressure urges head 12 upwardly such that the bottom surfaces of slots 44, 45 engage arms 51, 52 and lift the pin until it engages the upper surfaces of slots 46, 47, 49, 50, in which position 'O' ring 42 engages surface 41 to form a gastight seal. As long as the container remains pressurised pin 16 cannot be withdrawn. To refill or service the container, head 12 is manually depressed to align the head and neck slots and to break the seal. The container thus vents to atmosphere and pin 16 can be withdrawn to release the head for removal. The force required to depress the head indicates the residual pressure in the container, and valve 14 is operated as necessary to discharge fully before disassembly. In Figs. 4-7 a modified locking clip is shown.

Abstract: 941,366. Golf clubs. J. JOHNSTONE. Nov. 22, 1960 [July 22, 1960], No. 40153/60. Heading A6D. In a set of golf clubs having head portions 21 of successively increasing loft angles, the head portions are constructed such that their respective centres of gravity are spaced progressively further from the toe 26 of the head portion. Thus the centre of gravity 1 of the Number 1 iron is closely adjacent the toe of the head portion, whilst that 9 of the Number 9 iron is adjacent the heel 27 of the head portion, the centres of gravity of the intermediate clubs in the series being spaced between these two points. In one embodiment of the invention, the club heads are formed with a thickened portion 28, the end 31 of the thickened portion being widest on the number 9 club and narrowest on the Number 1 club, and the end 32 of the thickened portion being narrowest on the Number 9 club and widest on the Number 1 club. Alternatively, an additional piece of material may be added to the rear face of each club and located to bring the centre of gravity into the required position, or material may be removed from the rear face of each club head by means of shallow drillings therein, such that the material remaining is so distributed that the centre of gravity occupies the required position.
